I am new here and could use some advice from the incredible experience here!
I have a 4107-078 , which needs a motor and transmission
And a "donor bus” Grumman Flx 8V-71/v730
The label in the bus, 1980 Grumman Flxible
Bus Mdl# 53102-8-1
Eng# 8VA402035 Mdl# 8V-71 7087 4523
Trans# V-730 13371 axle ratio 4 5/9 : 1 ?
- - - - -- - - -- - - -
The trans. # plate reads... Model#? 23013542
I have the manuals for 4107 and the v730 conversion ligature (I’m not sure if it is complete, no wiring for 4107?)
And I will get the Grumman manuals If can use them.
1. Before I pull the donor motor and make the FlXiblex a "n0n-runner"...Will this motor/trans. Swap work? Electronic control??
If it is DDEC what does this mean for a swap? I have the whole Grumman. It runs and starts great. I think I want the air throttle and shifter?
2. Do I really have to cut/relocate a bolt in the cradle support bracket? Any reports of long term (RV) failures in the modified bulkhead? If properly reinforced?
3. Is there a big enough advantage/difference in the brakes or axle/rear to change it as well? (But not with the Flx’s transit 4 5/9 : 1 ?? rear gear)
Thanks for all the Great Information you all have here..
